IMPnovnn san-mon.

TO ALL' WHOM IT MAY CONERN; Y I A i Be it known that we, Jnssn S. BUTTERFIELD and Josnrn A. READ, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in the Sad-Iron and we'do hereby declare that the following is a full, clear, and exact description of the construction and operation of thesame, reference being had to the accompanying drawings, Vmaking a part of this specification, in which- Figure 1 is a side elevation of the said improved sad-iron. i

Figure 2, an end elevation ofthe base, and a sectional view ofthe handle of the same detached.

Figure 3, a plan view of the 'central portion of--the upper side of the base; and

Figure 4, a plane view of the under side of the handley Like letters of reference indicating the same parts when 4in the diierentjigures.

Our improvement relates to those sad-.irons-which have detachable handles; and the nature of our invention consists in the peculiar manuel', hereinafter described and specified, of constructing and applying the detachable handle to the base of the 'sad-iron, whereby a single handle can lbe attached to, and detached from, any one of a series of bases,` as occasion may require, with greater facilityand security vthan heretofore.

Referring to the drawings, A B are the base, andC Dfthe detachable handle ofthe saine. 0n the upper side of the base A B, and near its centre of gravity, a tapering circular projection, a', is cast, or otherwise fixed, which has two horizontally projecting sectors or portions a a, separated by two lateral spaces b b', and sloped or inclined in opposite directions on thcirunder sides, like the under side of the square screw-thread of a"vertical bolt or nut. The upper end of a has a deep. cavity in` its centre, and the circular boundary of the latter is notched and sloped, so as to form two oppositely inclined planes, a a". The handle C D has two feet crc, connected together above by a curved' plate, d', ivhichis broad enough to defend one's hand from the heat of the base A B While using the sad-iron legitimately. On the centre of the under side of el"A there is a conical stud orsteadying-pin, d, which will loosely tit 'in the cavity in the upper end of af,- andrat the opposite sides of its base there are two shoulders or sectors d d, which will come in contact with the respective notches of the two inclined planes of the upper end of a', IWhen the handle C D is t'o be detached from the base A B, and thus stop its movement4 at the proper place fordetaching. The feet c c of the handle C D haveeach adat, inward-projecting portion, c c, which will, respectively, pass down through the spaces b b', between the ends of the planes a a of the projection a', in applying the handle to the base, and -will also slide under the said planes a on turning the handle around toward the right hand.V In tig. 2 the handle is shown as in the transverse position requiredtoenter the parts c c and d,--as above described. Through a hole in the forward foot-end of the handle a drop-pin, eis placed, the lower end of which will drop into a corresponding holeisee dotted line e) in the base A B, when the handle is turned around into the position shown in iig. 1.

Operation.

Several of thc bases A. B (without handles) being placed on a heater, any one of them may be taken up and used 'by placing the handle C D transversely over the middle of the base A B, entering the`steadying-p`in d into the cavity in a', and the projecting ende c ofthe feet c c into therespective spaces b b', and then by turning thehandle around to the' right, so as to pass the said projections c c under` the projections'a a, and continuing the turning of the handle around Vto the right, the pin c drops into the h ole made for Vit inthe forward part of A B, thus stopping and securely attaching the handle in a moment, dctaching the handle on returning' the base to the heater, it is only necessary te raise thcdrop-pin e by the thumb and nger of the hand .which grasps the handle, anil then to turn the handle backtol its'rst position across the base, the sectors dlll'd catching against the notches which are between the two planes a" af, and thus stopping the rotary motion of the handle when the latter has reached the proper position to be lifted up or withdrawn. This is a very easily operated, eil'ectve, and durable device for the purpose. l

Having thus fully described our improvement in the sad-iron, what we claim as new therein of our invertA tion, and desire to secure by Letters Pat-ent, is confined to, the following, viz: l v

1. We claim the steadying-pin el, in combinationwith the sectors d, d on the guard-plate d', the said parts being constructed` and arranged to operate -in connection with the planes a a Ion the projection d', sub stantially as and for the purpose described. l

2. We claim the projection a on the base AB, with its two opposite sectors or inclined planes, a ai', constructed and arranged to receive and hold down the inward ends'c" c of the feet of the handle C D, substantially as described and set forth. l y

3. We claim the projecting ends e c of the handle C D, constructedand arranged to operate in combina= tion With the spaces 11'l In and planes a a", substantially as and for the purpose described. i
